Inline Declaration – In a select statement
Perhaps this is my favorite as the time saved with inline declaration is really significant and it also comes handy in maintenance and support of the program as it increases the program readability.
Without inline declaration
TYPES: BEGIN OF ty_matdoc,
mblnr TYPE mblnr, "Mat Doc
mjahr TYPE mjahr, "Mat Year
zeile TYPE mblpo, "Item
matnr TYPE matnr, "Material
charg TYPE charg_d, "Batch
ebeln TYPE ebeln, "PO
ebelp TYPE ebelp, "PO Item
END OF ty_matdoc.
DATA: t_matdoc TYPE STANDARD TABLE OF ty_matdoc INITIAL SIZE 0.
SELECT mblnr
mjahr
zeile
matnr
charg
ebeln
ebelp
INTO TABLE t_matdoc
FROM mseg
WHERE ebeln = lv_ebeln.
With inline declaration
SELECT mblnr,
mjahr,
zeile,
matnr,
charg,
ebeln,
ebelp
INTO TABLE @DATA(lt_matdoc)
FROM mseg
WHERE ebeln = @lv_ebeln.
Notice the changes:
- Comma after every field, except for last one.
- ‘@’ Used for all variables
- AND no need to remember the data elements for each field!! (Absolute winner)
In the custom program, due to modularization, sometimes it means that these tables will be local in nature. If I need a global table, I will go back to normal type declaration.
